Project No.: 2021/40/Q/NZ8/00006
This project seeks to use garden waste to produce the biochar, and immobilize the PAEs-degrading endophytic bacteria flora so as to reduce PAEs in soil-vegetable system.
The indigenous endophytic community will be domesticated and screened to make it have the ability of efficient degradation of PAEs, and then immobilized on the biochars.
Using the common leafy vegetables, fruit vegetables and root vegetables as test crops, the removal process and pathways of PAEs in the soil-vegetable system by biochar-immobilized endophytic flora will be elucidated. The form, availability and release of PAEs in the vegetable rhizosphere soil will be clarified, and the responses of microorganisms, enzymes, and PAEs-degradation genes in soil and vegetables will be characterized.
On these basis, the chemical and biological mechanisms of the PAEs removal soil-vegetable system by biochar-immobilized endophytic bacteria flora will be comprehensively clarified.
This project is not only expected to provide new ideas for the resource utility of garden wastes in China and Poland, but also provide a key theoretical technique for safe vegetable production in PAEs-contaminated areas. This project will deepen scientific research cooperation and exchanges between China and Poland.
